SOLVED: New PineTab2 not booting properly. SECONDARY PROBLEM SOLVED: Not updating

[diederik]

So i got a USB-C to Ethernet adapter but I can't seem to update, i get an error.

... Could not resolve host: p64.arikawa-hi.me

but i went to that address on my laptop and it's clearly there.

any suggestions?

1. Try if you can 'ping' your local router, which is often 192.168.1.1.
   
2. If that works, ping 1.1.1.1
   
3. If that works, ping debian.org
   

ad 1) If that fails, then your network connection doesn't work at all. My guess is that this is the issue. Look at the arch wiki on how to solve that.
The IP address on your PT2 and your laptop would normally be in the same subnet (192.168.1.x)
ad 2) this is unlikely to be the issue as it works from your laptop, but if it doesn't work then that would indicate an issue between your router and your ISP and via that, the internet
ad 3) If this is the culprit, then you have a DNS issue. Look at /etc/resolv.conf on your laptop and your PT2 and figure out why they are different.

Posting the output of `ip a` may be useful too.
